Dear Appeals and Grievances Department,

On behalf of [Hospital/Facility Name], we submit this formal written appeal contesting the denial of Claim TEST-CLAIM-00072, issued by Synthetic BCBS-TX on January 11, 2026. The claim was denied under reason code CO-16 ("Claim/service lacks information or has submission/billing error(s)"), resulting in a denied amount of $2,544.68 of the $5,969.35 total billed for services rendered on October 18, 2025. We respectfully request that Synthetic BCBS-TX overturn this denial, reprocess the claim in full, and issue payment of the denied amount upon review of the enclosed corrective documentation.

I. BACKGROUND AND BASIS FOR APPEAL

The services at issue were rendered on October 18, 2025, and billed under CPT codes 50499, 54541, and 56009, linked to diagnosis code I10.18. The denial issued under CO-16 does not reflect a determination of non-coverage or lack of medical necessity; rather, it indicates a perceived deficiency in the claim submission or coding. Because the basis for denial is a correctible administrative or billing matter — not a substantive coverage exclusion — we submit that the denial is inappropriate and that full payment is warranted upon review of the complete and accurate documentation enclosed herewith.

Our facility maintains that the CPT codes and associated modifiers as billed accurately and completely reflect the procedures performed on the date of service, and that those procedures are properly linked to the relevant diagnosis. We respectfully assert that any information identified as missing or deficient by Synthetic BCBS-TX is fully addressed by the documentation enclosed with this appeal.

II. PAYER POLICY AND APPLICABLE STANDARDS

Pursuant to Synthetic BCBS-TX's claim submission and billing accuracy requirements governing CO-16 denials, a denial issued on this basis is subject to appeal and correction through the submission of a corrected claim or supporting documentation that remedies the identified deficiency. The applicable policy recognizes that when a claim is denied for a submission or billing error rather than for reasons of coverage or medical necessity, the provider may cure the identified deficiency by supplying complete documentation — including operative reports and coding verification — that substantiates the accuracy of the codes and their linkage to the relevant diagnosis.

Because the denial arises from a correctible administrative matter, and because supporting documentation exists to demonstrate coding accuracy and medical appropriateness, this appeal is properly before the Plans appeals unit and merits de novo review.

III. SUPPORTING EVIDENCE

To address the CO-16 denial and demonstrate that CPT codes 50499, 54541, and 56009 — as billed with their respective modifiers and linked to diagnosis I10.18 — accurately reflect the services rendered on October 18, 2025, we have enclosed the following documentation:

1. Corrected Claim Form: A corrected claim form with complete billing information, verified procedure codes, applicable modifiers, and proper diagnosis linkage, submitted to address any identified submission deficiency.

2. Operative Report: The enclosed operative report documents in clinical detail each of the three procedures performed on the date of service (CPT 50499, 54541, and 56009), substantiating that the codes billed correspond precisely to the services performed.

3. Itemized Claim Submission with Coding Verification: The enclosed itemized claim provides a line-by-line accounting of procedure codes, modifiers, and diagnosis linkage, accompanied by coding verification demonstrating compliance with applicable coding guidelines.

4. Clinical Documentation Supporting Medical Necessity: Clinical documentation is enclosed that supports the medical necessity of each procedure billed in relation to diagnosis I10.18, further establishing the appropriateness of the services rendered.

5. Explanation of Procedure-to-Diagnosis Relationship: A written explanation is enclosed detailing the clinical and coding basis for the relationship between the procedures performed and diagnosis code I10.18, ensuring full transparency regarding the coding rationale applied.

Taken together, this documentation confirms that the claim as submitted was accurate and complete, and that no substantive deficiency exists that would justify a denial of $2,544.68 in billed charges.

3. Issue payment of the denied amount of $2,544.68 in accordance with the applicable contractual and plan payment terms.
